Abstract
A dual function coating on a counterface of a seal. The dual function provides having a low friction and being hydrophobic. This is achieved by chemically modifying a low friction coating. Gaps are included, primarily on the exterior side of a seal, one side being coated with the modified low friction coating on a counterface and the other side with a hydrophobic or omniphobic material on a seal body. The material can be in the form of a coating, film, strip, or ring depending on application, and be coated, glued, fused, mechanically attached or by any other suitable method, attached to the seal body. The gap should preferably be in the order of 0.2 to 1 mm wide, thus creating 'reverse-capillary' function where water cannot pass all the way through the gap.
